30,000 mAh power bank for a steal! This model costs less than five hundred crowns and has a display

A power supply for your phone and tablet doesn’t have to cost thousands. The white Vention 30,000 mAh power bank is available on Alza for 489 CZK with code ALZADNY30 and is in stock. The offer makes sense mainly for those who want to carry power with them and don’t need a small backup for their pocket.

Quick summary:
✅ Makes sense for: Shared trips when you share the power bank. According to the seller, it can charge up to three devices simultaneously.
⚠️ Consider: It weighs 587.5 g and has a depth of 39.94 mm. For everyday light carrying, this is a noticeable compromise.
💡 The code saves 210 CZK compared to the current public price. Without it, the power bank costs 699 CZK; this is not a member price.

You get different power via USB-C than via USB-A

The 22.5 W rating does not apply to every connector. The seller states this power for USB-A, while USB-C has a maximum of 20 W. So, with a cable terminated with USB-C on both sides, count on the second value. USB Power Delivery support is also listed in the specifications.

Two USB-A ports and one USB-C port are available, so you can use cables with both common connectors. However, the seller does not specify how the power is distributed during simultaneous charging. Therefore, the stated maximums cannot be taken as a promise for all connected devices at once.

The display shows the charge level, you can recharge it via USB-C

The remaining energy is shown on the digital LED display, so you can easily check the power bank’s status before leaving. According to the seller, you can recharge it via USB-C or microUSB with 18 W of power. If you already have a USB-C cable for your phone, you can use the same type of connector to recharge its own battery.
